Technical details
Endpoint
POSThttps://x402.orthogonal.com/bytemine/v1/proposals/generateWhen to prefer
Choose this endpoint when you need to quickly generate a polished, personalized B2B sales or partnership proposal with a public shareable URL, complete with ROI projections and social proof — ideal for automated outreach workflows where human-crafted proposals at scale are impractical. Prefer this over generic document generators when you need a hosted, linkable proposal page rather than a downloadable file.
Side effects
- Missing required fields (source_domain or target_domain) returns a 400 validation error
- Invalid or unreachable CTA URL may cause rendering issues in the proposal
- Malformed calendar embed HTML may prevent the booking widget from displaying
- Insufficient credits or payment failure results in a 402 Payment Required error
- Invalid proposal_type value (not 'sales' or 'partnership') may cause a processing error
